Application filed July 25, 1921. Serial No. 487,454.

To allwhom it may concern? 7 V Be it known that I; PERCY ALEXA DERCHARLES BA'rnsy a subject of the King of Great Britain, residing atEastwood, near Sydney, in theState' of New South Wales and Commonwealthof Australia,-have invented new and useful Improvements in; and

Relating to the Utilization of .Wave Motion, of which the following is aspecification.

of wave motioninto powerandhas been devised for theefiicient utilizationof such motion in industry and otherwise. 1

These improvements inand relating to the utilization of Wave motionfcomprise primarily the'harnessing of mechanicaldevices 1n variousarrangements to the wave motion and connecting said devices-topumpshaving ing said high j'pressure water to actuate or drive turbines orother "suitablelfluid eng ,p l, t v

1 According to this invention a vane; or :1 vanes 'on the end of apendulous leveradapted to be partly submergedf in coastal waters l"arearrangedon 'a pontoon or on a carriage Y or truck} with water tank fpressure reservoir "with'power transmission mechamcal gearing' pumps andturbine or other water endouble ended-levers carrying one I or more gineand power machinesi .The' pendulous i [preferably at such ananglethatthe ponvanes or leaves depend nom n 'overhead shaft and the incomingwaves and the outgoing backwash cause the vanes toswing to and fro. andthe upper endof said leversimpart reciprocatingmotion tocrank whenceconnecting rods operate ,piston rods of pumpscylinders; Springs'from a-fast 'structime are preferably"arrangedito limit the swing of thevanes.v 3 g Thepumps in motion fO ICG WatBIi IIItO- a reservoir to storeupf-and concentrate the flow or pressureand thence the'water is su pliedthrough a pipe to drive turbines or water wheelsiwhich 11111- 1; mayoperate a 1 dynamo or other machine-from whichp'owerc g 1 motor 22 0fmore or less ordinary construction also afiixed on the pontoon deck 17and may be easily transmitted; I

The pontoon truck or carriage isjmounte ed on arail'on an inclinedrunway or slope such as an open beach'andwith or without enclosingconcretetraining walls and 0011- This invention relatesfto' the"conversion- 1 scale. 'Fig; 3 illustrates an crete bottom. Said carriageis adapted to be moved up and down the inclined runway in harmony withthe tides so as to allow or constant depth of vane in the waves; The

inclined runway or slope however might be constructed over an;opencut orrace into Whlch the lncoming wavesliave access and 1n whlch the vane orvanes are part sub- 7 'merged. And the sides and walls inclined orotherwlse of the'cut or race may be in solid rock and be lined withcement concrete or be built entirely of cement concrete. I

In order that this invention may be readily carried into practicalefi'ect the preferred mechanical arrangement therefor will now'be'described w'ith reference to the drawings accompanying and forming partofthis complete specification.

The figures are all more or less schematic and Fig. 1 shows transverseand side secvane reciprocates in a water race and Fig. 2 a perspectiveview of same motoron a larger alternative form of wave vane, or pad,

Referringto Fig. '1 a pontoon lO is mountupon draughtwheels 11 whichtravel upon rails 12-laidupon an'inclined way or base constructed say,of cement concrete and inclining from'h igh land into the sea say awater'tank 13 and a pressurereservoir 14 indicated. by do tted linesinFig. 2. The tank 13 is connected by'su'ctionpipelti to verticalpump orpumps 16 affixed 011 the pontoon deck 17 and from which pump or pumps adelivery, pipe18 leads to reservoir tank 14 whicliflis fitted with anair chamber f 19 and it required Witha relief-valve (not shown).Discharge pipe 20 with control valve 21therein leads fromreservoir 14 tothe jet or inlet port 21 of a turbine orjwater exhaust pipe 23 from saidturbine 22 leads hack into the tank 13; I

he he he Nade high ly and outwardly from the deck 17 and near theiroverhanging forward ends have bearings for a transverse shaft 25 onwhose ends are crank discs 26 and outwardly again of these aregtulcrumedgthereon levers 27 WllOSB lower ends carry the vane 28 (inthis case a single rectangular and flat leaf) and whose upperendseachconneet-to a crank pin 29 on disc 26. A connecting rod 30 leadstron-i each said crank pin 29 to one of a pair'ojf oscillating beams 31connected'by' a stay rod 32.

In order to provide the most effective working of the wave notor thevane 28 is required to be submerged andto ibe in constant contact withand to an even extent at all times in the water and therefore thepontoon 10 should travel down and up the inclined way 12 in harmony withthe tides. Thisanovement may take place in any suitable manner and oneWay of accomplishing this is to placelaadraft hook 40 on the pentoon 10,that the pontoon may be moved along the railsl2;

The modified construction of multiple vane 28 shown in Fig. 3 has twopads or vanes 51 affixed :to an "arcuate member 552 reinforced :by bars.53.

Enclosing concrete training walls may :be if desired constructed at oneor on :both sides of the runways of ithe pontoons .or trucks toconcentrate and or direct .the waves.

In some ,cases as in ver 1 rough weather {though only ,veryexceptionally when a cut ,orrace with ihighvside walls is provided forthe wave vane the :pontoons and trucks may be ,advisedly drawn landward:clear of the waves.
